What's your disk configuration on this 8 core machine?
Are you implying/stating that the performance of the disk subsystem is
irrelevant WRT multithreaded unlink workloads with delaylog enabled?
If so, this CPU hit you describe is specific to this workload scenario
only, not necessarily all your XFS test workloads, correct?
